<?php

class Image {

private $image;

private $info;

public function __consstruct($src){

$info = getimagesize($src);

$this->info = array(

'width' => $info[0],

'height' => $info[1],

'type' => image_type_to_extension($info[2],false),

'mime' => $info['mime']

);

$fun = "imagecreatefrom{$this->info['type']}";

$this->$image = $fun($src);

}

public function thumb($width,$height){

$image_thumb = imagecreatetruecolor($width,$height);

imagecopyresampled($image_thumb,$this->image,0,0,0,0,$width,$height,$this->info['width'],$this->info['height']);

imagedestroy($this->image);

$this->image = $image_thumb;

}

public function show(){

header("Content-type:".$this->info['mime']);

$funs = "image{$this->info['type']}";

$funs($this->image);

}

public function save ($newname){

$funs = "image{$this->info['type']}";

$funs($this->image,image,$newname.'.'.$this->info['type']);

}

public function __destruct(){

imagedestroy($this->image);

}

}

?>

这是我的代码 报28行错误

public function show(){

header("Content-type:".$this->info['mime']);

$funs = "image{$this->info['type']}";

$funs($this->image);

}

求分析 十分感谢
